What reviewers say

Reviews find strong gaming performance, but little improvement over the Core i7-6700K. Overclocking results vary between samples and cooling setups. PCGamesN's later assessment finds Ryzen alternatives more attractive for heavily threaded work, while the processor remains capable in games.
